Serial communication error
A communication error between the DC Controller PCB and the Laser Driver PCB was detected.
(An error caused by software)
[Related parts]
- Laser Scanner Unit
- DC Controller PCB
[Remedy] Perform the following in the order while checking whether the error is cleared.
1. Check the disconnection of the Laser Scanner Unit Harness/Connector.
2. Check the disconnection of the DC Controller PCB Harness/Connector.
3. Replace the Laser Scanner Unit.
4. Replace the DC Controller PCB.
[Reference]
Before replacing the DC Controller PCB, back up the service mode data and restore the backup
data after the replacement so the data may be able to be protected.
- Backup: COPIER (LEVEL2)> FUNCTION> SYSTEM> DSRAMBUP
- Restoration: COPIER (LEVEL2)> FUNCTION> SYSTEM> DSRAMRES
